TELE GRAPH-SOUNDEE.

Specification of Letters Patent.

Patented Sept. 22, 1908.

Application filed November 18, 1907. Serial No. $02,625.

To a-ZZ whom it may-concern:

it known that I, LEE KIBLINGER, a citizen of the United States, and aresident of Jackson, in the parish of'East Feliciana and State ofLouisiana, have invented a new and improved Telegraph-Sounder, of whichthe following is a full, clear, and exact descrip tion.

My invention relates to telegraph sounds, my more particular objectbeingto provide the same with an improved form of electromagnct and arms luremating the same.

Ref once is to be had toil'ze accompany- 15 mg drawings iornnnga part orthis specification, in which similar-characters of reference indicatecorresponding parts in both the figures. k

Figure 1 is a fragmentary side elevation of 2a a sound r pr vided withmy improved electromagnet, the latter being partially broken a and Fig.2 is a fragmentary plan of Junder with its improved electromagnet turctherefor. e sl'iown at 3 and a base late at 4, beinr supported upon ugs5, 6, having its middle portion free to At 7 a yoke having substantiallyof an inverted-U. An armature mounted upon adjusting screws 9 'ch extendthrough this yoke. The armature lever is provided with an armature 10, fg the form of a wide flat plate and seto the armature lever by a bolt 11and i handle is shown at 13 and is pro den. with a lug 14 extendingupwardly and Jaclrwardly therefrom, Adjusting screws n at 15, 16 and aresecured rigidly in 'srtion by milled nuts 17, 18.

Cores 19 are connected together by a sin gle back plate 20, and arewound with flat spools 21, 22 of wire, insulated at the ends by plates23, of insulating material. The spools, cores and insulating platestaken together constitute a pair of elcctromagnets, each provided with aflat core 19. The two cores terminate in pole pieces 25, 26. The polepieces haye a width nearly equaling the extreme width of the armature10. so it will be noted that because of the flat shape of the.electroinagnets they can be made ver wide and placed with their polesclose together. Zecause of this fact, together with the shape of thearmature 10, and pole pieces 25, 26, the magnetic circuit iscomparatively short and corres ondingly powerful. The net result is t atthe magnet shown is capable of drawing the armature 10 with an'unusually strong impulse. The armature lever 8 is retracted by acompression spring 27 held in position by an adrusting screw 28, thelatter being secured by a milled nut 29 resting upon a lug 30. This lugis integral with the yoke 7.

The operation of my device is as follows: The magnets being energized,for instance by current from a local circuit, and being deenergized soas to produce Morse char; hers, or analogous signals, the armature isdrawn forcibly downward, carrying with it the armature lever 8. Theoperator, by listening to the sounds of the strokes, is enabled to readthe characters or signals in the usual manner. The magnetic circuitbeing comparatively short and powerful, as above described, thesuddenness of the click made by the descending armature lever is greaterthan usual, and the result is that less battery power is required for agiven degree of loudness of the sounder. Conversely, for the same amountof battery power the action of the machine is much more satisfactory.

The type of magnet shown, while in this instance applied to a sounder,may be used in relays, electric bells, and various other forms ofapparatus in which the magnet is employed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent: I

in asounder, the combination of a longitudinal armature lever, anarmatureconnected therewith, a pair of electroniagncts disposed adjacentto said armature and provided with wide flat pole pieces extendingdirectly across the general length of said longitudinal armature leverand disposed adj accnt to said armature l'or the purpose of equalizingthe density of the magnetic field between the armature and differentparts of the pole pieces.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
